Hi Vaibhav,
Thanks for your interest in Syncfusion products.
I am afraid that am unable to replicate the reported behavior on our end with the details provided.
Attached is the sample used to test the behavior here. Could you please modify the sample to reproduce the behavior and send it back to us with the version details of Essential Studio?, So that we can have the reported behavior addressed at the earliest.
Note : Mnemonic keys will invoke the click event of the control.
Please let us know if you have concerns on this.
Regards
Vallarasu S.
